As The BBC reports, Lucy had been missing for two days last month before her body was found in the woods near a sports center in Southampton, UK. She was stabbed to death.

Stephen Nicholson, a friend of the family who'd been staying with them, was allegedly in contact with Lucy the morning of her disappearance. Police took him into custody and asked him – twice – for his password so they could check out the alleged conversation and whatever other content might help the investigation.
